Wilo Yonos Pico 4169842 Commercial Central Heating Pump is rated 4.4 out of 5 by 23.
Rated 1 out of 5 by from Can't part electrical connecto It should be really obvious and simple but for the life of me I can't get the electrical connector to part so can't wire it up. I've been trying for an hour now. The manual shows exactly how it should part (although only on the last diagram where's it's not being parted but is in fact being put back together) but mine just won't and now the clip has broken. Very annoying.

Rated 5 out of 5 by from Simple Replacement Could not have been easier. As long as you can handle a wrench and a screwdriver, fitting as a replacement pump is foolproof.

Rated 4 out of 5 by from good quality pumps These are good quality and good value from Screwfix. I have been fitting Wilo Pumps for donkeys years and have found them to be as good if not slightly better than Grundfoss. have fitted a few of these Yonos ones since they came out and not been back to a faulty one yet.

Rated 5 out of 5 by from Great alternative to Grundfos Bought this to replace a noisy Grundfos 15- 50 130 pump. Straight swap out, super quiet and much lower energy consumption.

Rated 5 out of 5 by from Just buy one Perfect replacement for older Wilo pump. Remote electrical connection plug good when I figured out how to open the electrical contacts. Super silent in operation, 5 year warranty gives peace of mind.

Rated 5 out of 5 by from Wilo pump As a trades person,this was the easiest pump to fit (at least the old pump had rubber washers) and no fuss trying to connect electrics as remote plug to wire up and connect.

Rated 4 out of 5 by from Good Nice quiet pump. Easy to install. Usually fit grundfos but customer wanted a cheaper one. Seems good just not sure about reliability.
